S-92685A530 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 3 drill tip for direct penetration into steel and sheet metal up to 0.21" thick, saving significant labor time and tooling costs.
• Superior corrosion resistance from the zinc-plated steel construction, ensuring long-term durability and reliability in harsh industrial environments.
• Enhanced driving stability and anti-loosening provided by the external hex drive and serrated locking flange, delivering a secure, vibration-resistant fastening.
• Optimized thread engagement and holding power through the fully threaded, thread-forming (BSD) design, which creates strong, permanent threads in the base material.
• High-strength fastening for demanding applications with a robust 1/4"-14 thread and 1" length, designed specifically for steel and sheet metal assemblies.
• Streamlined installation process combining the self-drilling tip and external hex head for high-torque application with standard tools, maximizing efficiency.

Professional Applications & Engineering Value

This zinc-plated steel flanged self-drilling screw is engineered to solve critical challenges in metal fabrication and assembly. Its thread-forming BSD design and No. 3 drill tip allow it to penetrate and tap its own thread in steel and sheet metal up to 0.21" thick without pilot holes, drastically reducing installation steps and potential for misalignment. The external hex drive and serrations under the flange provide exceptional grip and resistance to rotation under vibration, making it ideal for HVAC, automotive, and construction applications where reliability is paramount. The combination of a fully threaded shank and corrosion-resistant zinc plating ensures a lasting, high-strength connection that withstands operational stresses.

Specification Summary & Compliance

This 1/4"-14 tapping screw features a right-hand thread, fully threaded round shank, and is manufactured to BSD (Thread Forming) standards. It adheres to standard inch system dimensional tolerances for consistent performance. The screw is compliant with RoHS and REACH environmental directives, ensuring it meets industry requirements for restricted substances.
